プレツサ駆動構造。 In a mechanical compressor drive structure for a refrigerating vehicle in which a compressor 1 for compressing refrigerant is driven by a vehicle engine 10, a plurality of pulleys 12, 1 having different diameters are used.
3 to the output shaft 11 of the engine 10, and the same number of pulleys 17 and 18, which are dynamically connected to these pulleys 12 and 13, to the input shaft 14 of the compressor 1 via power cut-off mechanisms 19 and 20, respectively. At the same time, a tachometer 21 having an external output mechanism is attached to the output shaft 11 of the engine 10 , and the output of the tachometer 21 selectively operates the power intermittent mechanisms 19 and 20 . Regardless of the output shaft 11 rotation speed,
A mechanical compressor drive structure for a refrigerating vehicle, which transmits rotational power at a certain number of revolutions or more to the input shaft 14 of the compressor 1.
